To reduce food waste, scientists are making labels that track produce as it spoils

This new label mimics the product's decline in freshness by forming a bumpy surface.

A new type of use-by label for milk bottles that decomposes as the liquid inside goes sour could appear on UK supermarket shelves later this year. Labels such as these, capable of telling consumers exactly when fresh produce has gone bad, are being developed by scientists who want to stop food from being prematurely discarded. … Read more

To slash emissions, industries must capture carbon and store it

Carbon capture and storage is the only way for many industries to significantly reduce emissions, according to Sintef scientist Kristin Jordal.

The technology to help limit global warming to 1.5˚C already exists, but there needs to be the will to use it, according to Kristin Jordal, an engineer and senior research scientist at the Norwegian research organisation Sintef. As coordinator of the CEMCAP project, she and her colleagues have been investigating how to reduce greenhouse gas … Read more

Maya and his colleagues … Read more

Sustainability is a ‘top priority’ for chemists

Greening chemical reactions includes cutting the amount of energy used and reducing the need for toxic solvents.

A group of chemicals known as bi-metallics could help the pharmaceutical industry become more environmentally friendly by cutting the amount of energy used to produce drugs, according to Professor Eva Hevia from the University of Strathclyde, UK, who says that sustainability is a top priority for chemists. She has been developing applications for mixed-metal chemicals, which combine … Read more
